Questions, Comments & Tests:
Producing Highest-Quality Small-Particle Colloidal Silver at Home

Below is a collection of experiences, comments and results based on empirical and personal experiences, actual tests, and questions from colloidal silver producers and users. This page deals specifically with our production method and specifically with lab tests of the colloidal silver produced by our generators.

Our home colloidal silver production method produces the highest-quality, stable and effective colloidal silver available. Our test results show this below. When I am questioned about other sites and claims on those sites, I reply to them with comments on this page.

We're covering a lot of ground. So let's jump into some of the issues and questions below. To get fast answers to the issues covered on this page, just click onto the questions below.

Why is Particle Size so Important?

From the internet, in my own personal research, I will share with you my personal notes regarding colloidal silver and silver particles:

True silver colloids are products that do not contain any protein or other additives and whose silver content is predominantly in the form of nanometer sized silver particles. The effectiveness of colloidal solutions increases with decreasing particle size. Particle surface area is what determines a colloids ability to react with its environment. Reactivity increases with increasing surface area. Particle surface area can be determined by measuring two important physical properties, namely, particle size and particle concentration. Effectiveness is defined as the ability of the colloid to react with its environment. The higher the surface area, the more reactive the colloid, hence the more effective it is in reacting with its environment.--

Why our generators and our production process are so valuable:

  • You are producing 1nm to 2nm particles when agitating the water (see the topics below).
  • As described above, these tiny silver particles are the agents for the most effective colloidal silver use.
  • Our generators and recommended production processes allow you to produce this highly effective form of colloidal silver for mere pennies per batch.
  • To increase the colloid particle concentration, simply increase production time.

What is "agitating the water,"
and what effect does it have on my own Colloidal Silver production?

There are those that say that agitating the water with an air bubbler has no effect on colloidal silver. While we understand that those who espouse this viewpoint are trying to build a case for selling their own, more expensive colloidal silver home production methods, you really need to understand that the simple process of agitating the water during production with an air bubbler does actually in fact produce measurable, testable results as to its efficacy. (Scroll further to view our independent test results.)

We show that this simple, inexpensive home production method will produce for you 1nm to 2nm micro-particle colloidal silver. We've always known that home production produces ionic silver. But agitating the water generates a balance of ionic silver and nanoparticle silver: a perfect end result for effectively producing quality colloidal silver at home.

We discovered, along with some other colloidal silver generator producers that "agitating the water" is invaluable to the colloidal silver production process. In fact, learning of the value of agitating the water was the final chapter in developing a very stable, high quality small-particle colloidal silver product at home, for mere pennies per quart.

I had been reading quite a bit about "agitating the water" to reduce the macro-particles often found in production of silver solution, to better stabilize the final product after production, and most importantly to generate a higher colloidal content. In viewing photos of agitated water, it became very apparent to me that all they were doing was pumping air through the water during the production process, thereby keeping up a constant state of agitation.

That led to purchasing a small aquarium pump to agitate the water while the generator was working. I had no idea how radically the end product would so positively change for the better! Whatever you do during colloidal silver production of your own, buy a pump (we offer one that I use every time I make Colloidal Silver). Agitate the water. It makes a huge difference in the quality of your end product.

But continue reading below for the discovery that truly caused us to realize what agitating the water can accomplish by generating small-particle silver, increasing the effectiveness of silver in water in applications to our health.

View below photos comparing the visual difference between colloidal silver produced without agitating the water (in quart jar on the left), and colloidal silver produced while agitating the water (the quart jar on the right):

At 12 Hours: The difference in appearance between batches of Colloidal Silver where the water is not agitated (the jar on the left) and where the water is agitated (the jar on the right) At 12 Hours At 2 Days: The difference in appearance between batches of Colloidal Silver where the water is not agitated (the jar on the left) and where the water is agitated (the jar on the right)
At 2 Days
At 3 Days: The difference in appearance between batches of Colloidal Silver where the water is not agitated (the jar on the left) and where the water is agitated (the jar on the right)
 At 3 Days
At 8 Days: The difference in appearance between batches of Colloidal Silver where the water is not agitated (the jar on the left) and where the water is agitated (the jar on the right)
 At 8 Days
At 10 Days: The difference in appearance between batches of Colloidal Silver where the water is not agitated (the jar on the left) and where the water is agitated (the jar on the right)
 At 10 Days
At 14 Days: The difference in appearance between batches of Colloidal Silver where the water is not agitated (the jar on the left) and where the water is agitated (the jar on the right)
 At 14 Days

As you can see, the difference in the 2 jars is striking. The colloidal silver on the left, produced by not agitating the water, is amber colored in only 12 hours, and continues to darken as the days pass.

The jar on the right, containing clearer colloidal silver, remained clear from the beginning, and continues to remain clear (and very effective) over time. (Note: Your colloidal silver does acquire "color" with longer production times. My family prefers a lower ppm <"parts per million"> product for our needs. If you prefer a higher ppm product that has a color, simply produce your product for a longer period of time.)

Here are the conditions of production of the above quarts of colloidal silver:

  • Both colloidal silver batches were produced with an 18V, 500ma DC output transformer for 3 hours.
  • Both colloidal silver batches were produced using new .9999 silver rods (from this website), with a Silva-Cap (also from this website).
  • The clear colloidal silver was produced with the air pump water agitator and low voltage transformer, found as a generator package here on this website, and as components on this page. The air pump hose was removed, and a second batch was produced, the result of which is the amber colored colloidal silver.
  • The only production difference between the two batches was the air pump agitator.

Conclusion: Agitating the distilled water during production of colloidal silver without doubt affects the end result of your colloidal silver product. By agitating the water, the colloidal silver end result is one that remains clear and stable over time.

What is the particle size of the colloidal silver produced with your generators?

You will read on many internet pages that for colloidal silver to be effective, particle size must remain smaller than 50nm (nm = "nanometer.")

Samples from the jars of colloidal silver produced above were shipped to a university lab to measure particle size. The process is called "TEM" (Transmission Electron Microscopy). You may read about the process here. * (see note below at the end of this section regarding TEM)

We shipped the samples for tests for these reasons:

  • We wanted to discover whether or not agitating the water actually made a difference in the colloidal silver end product.
  • We wanted to see if agitating the water did indeed produce smaller particles.
  • We waited 15 days after production so that if the smaller particles (if they actually existed) converted back to ionic silver (as some websites claim will happen when agitating the water with an air bubbler), would there be any tiny particles remaing?

Below is what I feel is the credible evidence of testing that substantiates our assertion that agitating the water during production will produce 1nm to 2nm size silver colloids.

Here are the TEM image results:

  • Sample 1 was produced using air pump agitation with the air pump available on this site. This image illustrates the higher number of very small colloidal silver particles, measuring 1nm to 2nm in size. The age of the sample at the time of testing was 21 days old.

  • Sample 2 was produced with no water agitation. Most particles imaged measure between 30nm and 50nm in size. There were no particles smaller than 20nm evident in this test. The age of this sample at the time of testing was also 21 days old.

The image below (21 days old at the time of testing, which allowed any silver oxide to revert to ionic silver) reflects the particle size that is generated as a result of agitating the water during colloidal silver production. The lab provided a measurement of average nanometer particle size of 1nm to 2nm. (This translates to .0010 to .0020 microns. One micron is 1/25,400 of an inch. The particles produced by our generators are therefore 1/25,400,000 of an inch in size.) These particles are identified by arrows at 200,000x magnification, in a product that was produced 21 days prior. Even smaller particles existed in the sample, along with larger, individual particles (as seen in the photo below). (The scale in the image reads: "10 nm.")

This image shows the Small-Particle Colloidal Silver Nano Particles produced by the Generators sold on this site

The image below is a typical image sample of the particle(s) created with colloidal silver production without the process of agitating the water. The sample was also tested 21 days after production, and produced an average size particle of 20nm to 50nm at 200,000x magnification. There was no evidence of individual 1nm to 2nm particles in the image sample below (as seen in the image above). Particles in Sample 2 appeared as "grape-like clusters." (The scale provided in the image below reads: "10 nm.")

This image shows that by not agitating the water during production that you will not produce the Small-Particle Colloidal Silver Nano Particles produced by the Generators sold on this site


  • By agitating the water, you are dramatically altering colloidal silver during production.
  • By agitating the water, you are indeed producing 1nm to 2nm particles in your colloidal silver solution.
  • Even after a waiting period of 21 days, to allow particles to revert to ionic silver, we continue to see a large number of 1nm to 2nm particles in the image of Sample 1. No particles of this size are visible in the image of Sample 2.

From the perspective of my and my family's personal use, agitating the water during production creates a highly stable, extremely effective small-particle colloidal silver product.

* TEM is in fact the method of choice to adequately measure particle size within the industry. The "science site" publishes claims to the contrary. Again, I refer to the article published by Hydrosol, producers of a high-quality colloidal silver product, as they prove through science the errors published by the producers of Mesosilver.

What is the difference between a "wide-mouth" jar and a "regular" jar?

Wide-Mouth and Regular Size Jars

There are a variety of reasons that we offer you a choice in jar type and size.

Mainly, it is because some customers have a lot of wide-mouth jars they wish to use in which to store their colloidal silver. Others just like the additional "working space" available on a wide-mouth jar lid. Either jar is an option, although the "standard" jar lid continues to be the most popular, and will be shipped to you as the default jar style if you have not made a choice during the shopping process.

Why is my TDS Meter not giving me the Parts Per Million (ppm) readings you say I should be getting?

TDS (Total Dissolved Solids) meters are perhaps the most common method individuals use to test their home-produced colloidal silver after production.

The controversy arises over the fact that off the shelf, retail purchased TDS meters are actually incapable of measuring colloids, and especially small-particle silver. TDS meters are actually designed to measure impurities in the water. They are incapable of measuring actual colloids.

Please refer to the images above illustrating the obvious visual difference between agitating the water, and not agitating the water during production. The amber colored product consistently measured 25ppm over time with a Hanna PWT meter, while the clearer product on the right consistently measured 16ppm. The production times, quality of silver, amount of DC voltage were all the same.

From pages on the internet, we find this valuable information concerning TDS meters and their lack of effectiveness in measuring colloid particles:

"In truth a TDS meter gives a more accurate reading of the purity of the water rather than giving a spot on count of silver colloids. Some of the leading manufacturers of TDS meters agree to this fact although the meters are widely used for counting silver colloids. The leading manufacturers agree that TDS meters are not the perfect tools for measuring the colloid count. On the contrary this is a perfect tool for gauging the impurities present in your distilled water. You will find TDS meters being promoted as effective tools for testing colloidal silver ppm when in truth it does not give you an accurate reading.

"In order to get a 100% accurate ppm you will be required to send your colloidal silver sample to a laboratory which is well equipped to analyze the CS. This could turn out to be a rather expensive and time consuming process. This is why most of the producers of CS make use of TDS meters despite the fact that they only give you a relative ppm of the sample.

"When using a TDS meter the reading obtained is written as the number obtained followed by ppm. Although the TDS meter does not give you a spot on accurate result but in general the results obtained are accurate enough to be used for basic purposes. This is because by making use of TDS meters you will not have to rely on guesses in order to determine the concentration of your CS solution."

A TDS meter is designed to measure impurities in water. Because we are agitating the water, we are generating minute suspended particles at a size of 1nm to 2nm, which is incapable of being measured by a TDS meter.

Ultimately, when using a TDS meter to check your colloidal silver production, please know that your meter is incapable of measuring colloids. It is only capable of measuring impurities in your solution.

Please scroll below to view the parts per million (ppm) comparisons during production times of an over-the-counter TDS meter, a PWT meter, and actual colloidal content on colloidal silver tested by our generators.

I want to make higher 'parts per million' colloidal silver.
Is it possible with your generators?

Yes. Simply produce your colloidal silver for a longer period of time. See the lists above.

Know that you will see an exponential increase in colloid content with longer and longer production times.

We suggest that you increase your production time in half hour increments until you reach the desired level of colloidal content.

I forgot to keep an eye on my colloidal silver production and have allowed it produce WAY too long.
Should I just throw it away?

No. You can salvage the colloidal silver you have produced:

1. You may pour up (and filter) the solution you have just produced, and use it as a very powerful, safe topical antiviral/ antibacterial solution for topical areas on your skin and living surfaces.

2. You may literally salvage your colloidal silver for consumption (because it will be extremely high in colloidal content) by diluting your solution with distilled water. The formula you may use to distill your solution can be relative to the amount of the extra time of your production period. For example, if your production period continued an additional 2 hours, begin by diluting your now-stable solution by filling a clean jar 2/3 with your solution, and adding distilled water. Using your meter and/or your laser pointer to determine strength, continue diluting until you reach your desired level.

I recently allowed production with a 24V transformer to slightly exceed 5 hours. My normal production period is 3-1/2 hours. I reached the desired level of colloid density with a 50/50 dilution with distilled water. After continued testing days later, I found that my colloidal silver remained stable and effective over time.

I am now reading that "ionic silver" is really the only effective form of colloidal silver that I should be producing and using. Do your generators produce any ionic silver?

Yes. Regardless of what you read on other websites, if you are using AC or DC electricity to make colloidal silver (which we who produce colloidal silver at home are using by default), you are creating a process called "electrolysis." The process of electrolysis by its nature generates ionic silver and particles. The bottom line truth is this: If you are producing collodial silver with electricity, you are also producing ionic silver.

The step we are taking that changes things for the better is agitating the water during production, thereby creating a far larger quantity of very, very small silver particles. Both ionic silver and small particle metallic silver are beneficial to support health.

You can easily measure ionic silver with an instrument that only measures ionic silver, called a "PWT meter" available at several online websites.

Listed below is the ionic silver content produced by our 24V electric "Basic Kit" after specific production times:

Production Time:
"PWT" Meter
(measuring ionic silver):
2-1/2 hours 8ppm
3 hours 12pm
3-1/2 hours 20ppm
4-1/2 hours 28ppm
5 hours 35ppm

Is there any harm in consuming small-particle silver?

Regarding consumption of small-particle silver, here's what we've discovered regarding testing:

(After testing), no clinically important changes in any metabolic, hematologic, or urinalysis measure identified were determined. No morphological (or structural) changes were detected in the lungs, heart (cardiac function) or abdominal organs. No changes were noted in sputum reactive oxygen species or in pro-inflammatory cytokines.

Conclusion: In-vivo oral exposure of a commercial 10-ppm silver nano-particle solution over 3-, 7-, 14-day exposures does not exhibit clinically important changes in metabolis, hematologic, urine, vital sign changes, physical findings or imaging changes visualized by MRI.

-- by Munger, Radwanski, Stoddard, Shaaban, Grainger, Yost at University of Utah

Frankly, in the dosages described above, over the years I have consumed colloidal silver, I have encountered no ill effects. The “blue man” syndrome ("argyria") we’ve all been frightened into believing is a risk, can only be experienced, from my reading and personal use, if you produce colloidal silver 100x stronger, and consume upwards of 1 quart to 1 gallon of this super-strong solution per day on long periods of weeks and months.

There is also evidence that persons adding salt or saline to their water during production are generating extremely large amounts of silver chloride, which can be harmful in large doses, and is thought to create the “blue man” syndrome. So I don’t recommend using salt or saline during production.

And there's even evidence now that proteins added to keep the silver particles in suspension may also contribute to argyria.

However, with that said, I do recommend that you begin your colloidal silver regimen with the lowest ppm product (12ppm) and, if you are taking colloidal silver as a mineral supplement, stay with this ppm level for a while until you find yourself requiring or needing more to achieve the results you desire. If you experience ANY negative side effects that you feel might be related to the consumption of colloidal silver, immediately stop its use and contact your natural health professional for advice. Negative side effects are virtually non-existent, but possible. So responsibly begin colloidal silver in low ppm colloid densities and increase densities and consumed amounts gradually.

How much colloidal silver should I consume?

I use colloidal silver as a nutritional supplement, to enhance the level of health in my body by better enabling my body to care for itself. Therefore, during the summer months, I hardly take colloidal silver at all because (fortunately) I and my household are generally quite healthy.

During the fall, winter and spring months, I generally take 1 Tbl. of the 12ppm colloidal silver per day, especially when I become aware that there are colds and flu in the air. I then increase dosages and numbers of dosages throughout the day if I feel that I am possibly becoming ill. For children, the general consensus is that they take half the adult amount. But as always, for recommendations on consumption amounts, please consult your natural health practitioner.

Most often, though, I now take colloidal silver via a nasal mister and inhaler mister. These methods provide me with superior protection over time, and require that I make colloidal silver far less often. This also means that I am producing less colloidal silver than before, and therefore my silver rods are lasting even longer!

top of page

Is it possible to consume too much colloidal silver?

This is one of those very controversial questions that I receive on occasion. You'll find lots of information about this topic online, so I am going to simply share my own experience.

A couple of years ago, I began to experience what I thought was an intestinal virus. I began to consume large quantities of colloidal silver to attempt to remedy my situation. I was generating and drinking 1 quart of small-particle silver per day. I did this for 2 days.

I only determined at the end of the second day that my problem was not an intestinal harmful bacteria or virus. It actually was something muscular. But it gave me the opportunity to see what would happen if I took many times the recommended dosage of small-particle silver in a short amount of time, at a time when my body did not require treatment with colloidal silver. So, realize that I had just consumed 2 quarts over a 2-day period when my body did not need colloidal silver.

By the end of the 2nd day, I had developed diarrhea, and it continued through the night. The next day, I raced to my local retailer to purchase a bottle of live intestinal cultures. I took 3x the daily recommended maintenance dosage, every 3 hours, and my intestinal functions returned to a normal state in about 12 hours.

Obviously, a certain amount of care should be taken when consuming small-particle silver. So, the flip side of this is that when I am consuming colloidal silver to treat an ailment, my body seems to "inhale" this amazing substance, and I do not experience negative side effects, even when I consume large quantities. I think the important point is that, when it will positively aid your body in healing itself, small-particle silver is a safe and effective alternative to pharmaceutical drugs.

I live in Europe.
Will your generators work outside the US?

For customers outside North America, please know that all the electrical appliances accompanying our generators operate on 120V, 60hz AC electrical current.

Chances are your own AC electrical current is 220V to 240V. You will be required to use voltage adapters for our appliances to work properly. Altering our appliances for your electrical receptacles, and sending 220V to 240V through them will irreparably damage them.

We urge you to purchase your adapters in your home country. Adapters can be purchased at stores featuring travel accessories. Let the seller know that you need to adapt 120V appliances manufactured in the US, and they should provide you with the voltage converters you will need to ensure our products will work with your country's electrical systems.

I keep getting 2ppm to 4ppm readings with my TDS meter.
Is this a correct reading?

Depending on the quality and type of TDS meter, you could potentially get a wide variety of ppm readings. Remember that a TDS meter is designed to measure only impurities in the water.

My experience includes the use of 2 types of meters:

1. Off-the-shelf $15 to $30 TDS meters always provided me with a reading of 12ppm to 14ppm with my colloidal silver when I did not agitate the water (after 4 to 5 hours production time with a 12V DC transformer). After agitating the water, there was a marked reduction in ppm readings. Typically, my readings measured only 2ppm to 4ppm, but my colloidal silver was actually more effective in uses, remained stable in color and taste over time, and never lost effectiveness with age. I was perplexed, to say the least. That's when I discovered that TDS meters are incapable of measuring colloids (see above).

2. The Hanna PWT meter is sold online for between $80 and $100 (with the calibration solution). This meter measures only ionic silver. However, their instructions will tell you that your measurement of ionic silver will provide you with the relative silver content number of colloids. The very same colloidal silver solution I produced as described above measured 25ppm when I did not agitate the water, and 16ppm when I did agitate the water, using this PWT meter.

Conclusion: I experience roughly a 40% reduction of ionic silver when agitating the water, but a dramatic increase in small-particle colloidal silver (based on lab tests).
The end result is an amazingly superior colloidal silver product containing both beneficial ionic silver, and the presence of particles measuring 1nm to 2nm in size.

Based on tests conducted on the colloidal silver produced by our 24V electric generators, while agitating the water during production, these are the readings you can expect from home meters vs. actual colloidal content:

Production Time "TDS" Meter: $14.95 "PWT" Meter: $80 Particle Content:
2-1/2 hours 3ppm 8ppm 12ppm
3 hours 5ppm 12ppm 20ppm
3-1/2 hours 7ppm 20ppm 32ppm
4-1/2 hours 12ppm 28ppm 45ppm
5 hours 15ppm 35ppm 60ppm

What Parts-Per-Million of colloid content do you produce for your use?

Personally, we produce a retail-level of parts per million (ppm) for daily oral consumption of colloidal silver as a mineral supplement. This level is 20ppm, and can be produced based on the chart above for the production times listed. (Each generator kit purchase includes guidelines for a variety of ppm levels of production.)

At home we produce a much higher ppm concentration (50ppm to 60ppm) for our nasal, oral and bottle misters. We discovered that the level of effectiveness vastly increases with a higher colloid concentration. I also use the higher colloid concentration when treating an affliction. These higher levels can be achieved (see above) by allowing the production process to extend for approximately 2 more hours.

What does the laser pointer beam look like so I will know when my colloidal silver is ready?

Capturing the laser beam with a standard digital camera accurately is a bit of a challenge. However, the image shown here does show a fairly accurate image of the beam strength of the colloidal silver using a 12V DC transformer (the one sold on this website) with 4-1/2 hours of production time. This silver particle product measures 16ppm of ionic silver (see above) because the water is agitated.

Remember to check your colloidal silver with the laser beam in a darkened room. And be sure to allow the water to calm prior to checking.

I see gray “gunk” beginning to form on one of the silver rods.
Should I be concerned?

During the course of production, it is not unusual to begin to see a gray coating forming on the negative silver rods (those that have the black alligator clip attached to them). This is simply silver oxide, is harmless, and is a by-product of producing colloidal silver with electricity. Use of electricity is the only method available to produce colloidal silver at home. Know that if you are producing 12ppm level colloidal silver, you will probably only see a light “graying” of the negative rod and little or no silver oxide. For longer production periods, more silver oxide will form until you may even see some of the mass break away and float in your silver solution. This is nothing to become alarmed about.

At the end of a long production period, after you have wiped your silver rods clean, gently buffed them and put them away, pour your silver solution through a funnel lined with 2 coffee filters into your clean storage containers. This will capture most all the silver oxide formed during production.

As a tip: You may allow your colloidal silver to sit / rest for 2 or 3 days. Silver oxide is heavy, and fine particles of silver oxide that may not have been trapped by the filters after production can settle to the bottom of your storage jar. Simply pour this solution through 2 more coffee filters if you find silver oxide has settled. You will notice that the settled silver oxide will usually remain in the bottom of the original jar, and can be cleaned easily with soapy hot water.

Know also that the presence silver oxide does not affect your silver nanoparticle reading, nor your ionic silver readings. Because there was some controversy regarding the presence of silver oxide and its possible influence on particle readings, we allowed our own colloidal silver to rest for 15 days prior to lab testing. So know that you will get the same readings immediately after production that you will get weeks and months after production. Agitating the water with an air bubbler generates a completely stable and effective end product.

Which low-voltage transformer do you use, and for what length of time to you produce your colloidal silver (or what ppm reading do you like best)?

I personally use a 24-volt transformer when I produce colloidal silver at home for myself and my family.

Years ago, before learning of the value of agitating the water with an air bubbler, I discovered that a lower voltage 12V DC transformer produced the cleanest end result (in my opinion). However, when agitating the water, I can produce a clean, stable, effective product even at higher voltages, and do it in a shorter amount of time if I am agitating the water and using a 12V DC tranformer for 5 hours to generate a relative silver content of 16ppm (based on the PWT meter), I discovered I can use a 24V tranformer for 3-1/2 hours and accomplish the same thing.

So I and my household use the 24V Basic Kit found here on this website. I produce colloidal silver (while agitating the water) for 4-1/2 hours to generate a 45ppm colloid content. I have grown to prefer the higher colloid content because it is more effective more quickly when consuming orally. It's also very effective when using in a nasal mister, an oral mister inhaler, in eye-droppers, when spraying onto surfaces to disinfect in your home, and on your body to deal cuts, wounds, sunburns and fungus outbreaks. You can find all those items on our site here.

In the interest of producing a quality product in a shorter amount of time, I use the 24V transformer kit. However, all 3 of our kit designs will produce the same quality level of colloidal silver when following our production time guidelines.

Can I use filtered water, or "purified" water during my colloidal silver production?

Very simple answer. No. Only use distilled water during production.. Please also see the discussion above.

Image of the potential result of using anything other than distilled water in colloidal silver production.The reason is very simple. Distilled water is completely free of any elements other than the water molecule. Filtered and purified water contain minerals that can react adversely during the electrolysis process, bonding with the silver in ways that will at least produce a less than optimal product, and at worst produce a harmful one.The reason is very simple. Distilled water is completely free of any elements other than the water molecule. Filtered and purified water contain minerals that can react adversely during the electrolysis process, bonding with the silver in ways that will at least produce a less than optimal product, and at worst produce a harmful one.

The image here is an actual photo submitted by a customer who used what she thought was pure distilled water. She had admitted that she thought the water might have been contaminated prior to production of colloidal silver. You can see that there are compounds existing in the water that become visible and produce a less than ideal end result. Without understanding what compounds have been formed, you are never sure if consuming this product will be harmful or safe.

But if you wish to try it, I understand. I was one of those kids who my mom told me not to touch the flame because I could get burned. But I had to touch it anyway, just to see for myself. And sure enough, I got burned. So, try it once just to see what the end result is, only if you are curious. My suspicion is that you will have an end result that will be cloudy, and vary from black to yellow in color.

If you wind up with this result, just dump the mixture, go buy a gallon of distilled water, and begin again. And if you used store-bought distilled water and generated the cloudy, dark result, try purchasing another gallon. If you get the same result, purchase another distilled water brand from a natural health store. It's worth even a dramatic increase in the price of your water to get the quality of colloidal silver you need to be getting from your home production.

How long will my silver rods last?

As you have viewed on the site, I sell ONLY .9999 silver rods. It means the rods are 99.99% pure. It's the purest silver I can locate and it's the only silver I use. And it's 10x more pure than .999 silver rods. I only want purity with my personal product, and I presume you do too.

I have been very satisfied with the life production expentancy of 14-gauge .9999 silver rods.  It's an affordable product, and extremely pure.

I have used the same rods for about 3 years.  Three years ago I was producing roughly 1 to 2 quarts of colloidal silver per month.  That gave me roughly 75 quarts with these rods.

Then, a couple of years ago, I began primarily using nasal and oral misters for health maintenance, and my consumption of colloidal silver dropped enormously.  I basically stopped drinking colloidal silver unless I found myself fighting off a bug or the flu.

Today, I make about 12 quarts a year on average, depending on the time of year as well.  And I still have quite a bit of life left in these rods!

You will notice over time that they will appear to "shrink" in size as more and more silver is utilized in your production procedures. 

Based on my usage, and in the beginning years of my personal production, I would very conservatively say that you can anticipate producing at least 50 to 75 quarts of high quality small-particle silver with a set of $25, .9999 pure silver rods.

As a heads up: Please be wary of WAY underpriced "pure" silver rods. Silver is truly one item that can be said that you'll get what you pay for. Do you realize that visually you cannot tell the difference between .999 silver and .9999 silver? Yet, the .9999 silver is 10x more pure than .999. So, if you're getting .9999 silver at the same price as .999, or if you are seeing 12-gauge silver rods at the same price as 14-gauge (12-gauge is larger, thus containing more silver weight, and is usually much more expensive), please be cautious.

I've heard that you have to be careful about using commercial silver because it may have come from China, and could have ingredients in it that could be potentially harmful. Is this true?
What is the origin of your silver?

To me, this is actually a legitimate concern, and is information you should have prior to purchasing silver for colloidal silver production. "What is the origin of the silver I will be using? Do you have a Material Certification for the silver I will be using?"

 Our silver is .9999 pure (that is, it is 99.99% pure silver, and is the purest silver we are able to purchase).

If you find pure silver for sale online at incredibly low prices, you probably should be suspicious. I wanted to provide you with this information prior to purchasing, I wrote to our longtime, trusted silver supplier to find out the origin of our silver, and requested a Material Certification of our silver's contents.

Here's their reply regarding origins:

"Our fabricators are located in the US and comply with the Conflict Minerals section of the Dodd Frank Act.  The wire can be milled from silver bars (Comex etc.) or coins (Silver Maple Leafs, generic rounds etc.). It’s hard to say because a batch of the wire can have many sources. We just specify that it assays at 99.99% silver."

Below is the Material Certification of the .9999 product sold of this site:

How much colloidal silver do I make at a time?

For personal use, I usually make one quart jar at a time. This quantity will normally last me up to 2 to 4 weeks if I am taking 1 to 2 Tbsp. per day as a mineral supplement (sometimes I just forget to take it, and at other times family members are joining me in taking it, which accounts for the big time variance in how long the colloidal silver will last).

However, since I have been using the nasal mister on mostly a daily basis, I and my family use much less colloidal silver, and a quart jar can last 2 or 3 months (depending on the time of year), and still retain its clarity and stability.

Which generator do I use (battery-powered or low voltage plug-in electric)?

I use the 24-volt DC transformer most often. I use the battery-powered device when an electrical plug is either not available, or I don't want to string an electrical extension cord across a room. The battery-operated devices work well when traveling by car. When traveling by plane, I take the 24-volt electric transformer in my suitcase and store it with my other chargers (phone, camera, etc.) In terms of simplicity, I use the 24-volt transformer primarily.

The value of the battery-powered generator is if you have lost electricity as the result of a power outage, if you live off the grid or on a boat or in a motor home, or if you are on the road a lot, you can take this one with you anywhere. It's also great to have on hand so that you can produce colloidal silver anytime, anywhere, in an circumstances.

How do you store colloidal silver, and how long does it last?

I store my small-particle colloidal silver in a glass jar. Mine happens to contain a metal lid (it's a basic canning jar) but the metal lid has never seemed to have an effect on the colloidal silver itself. I then store the jar in the dark in a kitchen cabinet.

During a particularly challenging health time in my household a while back, I began just leaving the jar of colloidal silver out on the kitchen cabinet available for family members to use. It was just a matter of convenience to leave it out. What I was not aware of was that during the afternoons when I was not at home, the jar was sitting in full sunlight for several hours. After a few days I discovered that the colloidal silver was becoming a bit cloudy as it apparently responded to the UV rays of the sun. From then on, I began always making sure the jar of colloidal silver was returned to its place in the kitchen cabinet away from direct sunlight.

Prior to learning the incalculable value of agitating the water during production, I simply produced colloidal silver by attaching alligator clips from a low-voltage transformer to silver rods dipped in distilled water. Over the years of colloidal silver production with this method, I began to recognize the "yellowing" of the colloidal silver beginning almost immediately after production. And then the color became darker and darker. I will use the term "the color of beer", but other descriptions come to mind as well :). What I began to notice was as the colloidal silver became darker, there seemed to be a drop in effectiveness as well, in dealing with health issues.

Then I began to agitate the water during production (see above). One of the many results of agitating the water is stability and longevity. Since I began using misters as my preventative measures to ensure health, I use (and produce) far less colloidal silver than I used to. As a matter of fact, during the warmer months of the year, when consumption of colloidal silver in our household is quite low, it is not uncommon for me to have a jar of colloidal silver in the kitchen cabinet for 6 months! And I will tell you that my 6 month old small-particle silver is just as effective as the day I made it. It also remains just as clear as the day I made it as well.

This stuff's amazing! But of course, you already know that! That's why you're here... to educate yourself by learning from others, and by discovering places where you can get the supplies you need to produce this phenomenal product!

How do I know when the colloidal silver is ready?

I use a pen laser light shining through the jar during colloidal silver production (pen lasers are available on this site). It is interesting to shine the light through the jar through the distilled water before beginning to make small-particle silver. You will see no beam. The water is pure. Within 20 or 30 minutes, shine the light through the water again. You will begin to see particle reflections early on in a beam that will become visible. After a few hours of production time for quart jars, in a dark room, when I see a denser, but translucent beam of light shining through the jar, I know my small-particle silver is ready. And, as explained above, this provides me with a product measuring 16ppm of relative silver content with a PWT meter.
